Full skill instructions

Domain-Driven Design

Use this skill when

  • You need to model a complex business domain with explicit boundaries.
  • You want to decide whether full DDD is worth the added complexity.
  • You need to connect strategic design decisions to implementation patterns.
  • You are planning CQRS, event sourcing, sagas, or projections from domain needs.

Do not use this skill when

  • The problem is simple CRUD with low business complexity.
  • You only need localized bug fixes.
  • There is no access to domain knowledge and no proxy product expert.

Instructions

  1. Run a viability check before committing to full DDD.
  2. Produce strategic artifacts first: subdomains, bounded contexts, language glossary.
  3. Route to specialized skills based on current task.
  4. Define success criteria and evidence for each stage.

Viability check

Use full DDD only when at least two of these are true:

  • Business rules are complex or fast-changing.
  • Multiple teams are causing model collisions.
  • Integration contracts are unstable.
  • Auditability and explicit invariants are critical.

Routing map

  • Strategic model and boundaries: @ddd-strategic-design
  • Cross-context integrations and translation: @ddd-context-mapping
  • Tactical code modeling: @ddd-tactical-patterns
  • Read/​write separation: @cqrs-implementation
  • Event history as source of truth: @event-sourcing-architect and @event-store-design
  • Long-running workflows: @saga-orchestration
  • Read models: @projection-patterns
  • Decision log: @architecture-decision-records

If templates are needed, open references/​ddd-deliverables.md.

Output requirements

Always return:

  • Scope and assumptions
  • Current stage (strategic, tactical, or evented)
  • Explicit artifacts produced
  • Open risks and next step recommendation

Examples

Use @domain-driven-design to assess if this billing platform should adopt full DDD.
Then route to the right next skill and list artifacts we must produce this week.

Limitations

  • This skill does not replace direct workshops with domain experts.
  • It does not provide framework-specific code generation.
  • It should not be used as a justification to over-engineer simple systems.

AGI Framework Integration

Adapted for @techwavedev/​agi-agent-kit Original source: antigravity-awesome-skills

Memory-First Protocol

Retrieve prior Architecture Decision Records (ADRs), trade-off analyses, and system design rationale. Critical for maintaining consistency across long-running projects.

# Check for prior architecture/​design context before starting
python3 execution/​memory_manager.py auto --query "architecture decisions and trade-off analysis for Domain Driven Design"

Storing Results

After completing work, store architecture/​design decisions for future sessions:

python3 execution/​memory_manager.py store \
  --content "Architecture: event-driven microservices with CQRS, Pulsar for messaging, Qdrant for semantic search" \
  --type decision --project <project> \
  --tags domain-driven-design architecture

Multi-Agent Collaboration

Broadcast architecture decisions to ALL agents so implementation stays aligned with the chosen patterns.

python3 execution/​cross_agent_context.py store \
  --agent "<your-agent>" \
  --action "Completed architecture review — ADR documented, trade-offs analyzed, team aligned" \
  --project <project>

Control Tower Coordination

Register architecture tasks in the Control Tower so all agents across machines know the current system design and constraints.
